Disabling VM (the Paging File) can also have the opposite effect and slow things down. When you close a program a lot of times Windows will put that program in the paging file. Next time you start the program again it will start from the paging file, instead of needing to be re-pieced together off the hard disk (that's the technical term "re-pieced-together"
) This makes for faster load times. Trust me, the VM is there for a good reason. Don't disable it unless you know what you are doing, or you try it and you think it works for you. (But if your computer starts to really slow down - remember that paging file!)
